Hi,
I have an NVIDIA Quadro M5000 card installed in a workstation, and have all four DP ports hooked up to four 4K monitors (2x2 Mosaic). I Installed CentOS 7, Nvidia Driver 375.39, and xorg.conf configured properly. I have a huge 7680 x 4320 desktop now. Yum.
The issue is that if i use a media player like mpv to play a 6k movie (6240x2700) using vdpau driver, it gives me this error:
VO: [vdpau] 6240x2700 yuv420p
[vo/vdpau] Video too large for vdpau.
Could not initialize video chain.
When I run vdpauinfo, it gives me this:
display: :0 screen: 0

I’m wondering why the 444 and larger video surfaces are missing here? Not sure what i’m doing wrong here. M5000 supports these formats according to: Appendix A. Supported NVIDIA GPU Products and https://developer.nvidia.com/video-encode-decode-gpu-support-matrix
